seeing what yal think about xcons in my box

Just trying to see how you guys think 3 10"xcons would do in a 4th order that is 2.2 sealed and 4.5 ported before displacements. I know a lot of thing matter but The reason I'm asking is because that's the box I have my 15" zcon in . Its ported though the rear deck with removable port ( could make any tuning that would be good for the xcons) but not really wanting to do a new box right now cause its built in the car and I'm wanting to get louder. Loudest so far has been 145.6 and cant seem to get louder. .... would be at least doing rms. I have ho alt. 2 runs of 0 .close to 300ah of batts. lots of deadener .. let me know any questions you may have. Thanks
